Abstract
A medical instruments sterilization container (10) includes a housing (12) and a removable dome-shaped lid (14) having a filtered inlet port (18) disposed therethrough for permitting the passage of gas or steam into housing (12). A removable tray (16) is adapted to be disposed within housing (12) to hold various instruments to be sterilized and includes apertures (24) formed on the bottom of the tray for permitting condensate to drain therefrom. The bottom surface of housing (12) is sloped to two locations centered on opposite sides thereof and includes filtered outlet ports (40, 42) positioned at the two locations to permit discharged air and condensate to exit housing (12). Pedestals (30) are secured on the bottom surface of housing (12) to facilitate stacking of a plurality of sterilization containers.
Claims9
A medical instrument sterilization container comprising:
- a housing having a bottom and sidewalls and dimensioned for receiving medical instruments for sterilization by gas or steam, said housing bottom sloping to at least one location to drain condensate generated during the sterilization process to said at least one location;
- at least one pedestal member coupled to said housing bottom for supporting the container and for interacting with a portion of another similarly constructed container to permit stacking of a plurality of containers;
- a removable dome-shaped lid for said housing for enabling access to said housing and for creating a sealed volume therein to thus maintain the sterility of the interior of said housing;
- one filtered outlet port disposed in said housing bottom at each of said at least one location for allowing the passage of condensate therethrough and for also allowing air compressed toward the housing bottom by the passage of steam through said lid to exit said housing;
- and
- a filtered inlet port disposed at the highest point of said lid for allowing the passage of the sterilizing gas or steam therethrough, said inlet port disposed at a height such that it is vertically above and laterally offset from each of said at least one outlet port of an upper container when a plurality of containers are arranged in a stacked configuration.
A sterilization system for sterilizing medical instruments by gas or steam in a sterilizing chamber comprising:
- upper and lower containers configured to be stacked one upon another in a sterilizing chamber;
- each of said containers having a domed lid with a filtered inlet centered in the top thereof for receiving gas or steam and further having filtered outlets on the bottom thereof, said outlets being vertically and laterally spaced from said inlet such that steam or gas exhausting from said upper container exits said upper container at a point vertically below and laterally offset from the inlet of said lower container and thus does not enter the inlet of said lower container.
A sterilization system for sterilizing medical instruments by gas or steam comprising:
- a gravity steam sterilizer having a chamber, said chamber including an inlet port disposed proximate the top of said chamber for permitting the passage of condensate and air generated during the sterilization process to exit said sterilizer;
- a plurality of sterilization containers for being disposed in said chamber and arranged therein in a stack, each of said sterilization containers comprising:
- a housing having a bottom and side walls and dimesioned for receiving medical instruments therein;
- a removable dome-shaped lid for enabling access to said housing and for creating a sealed volume therein to thus maintain the sterility of the interior of said housing;
- a filtered inlet port disposed on top of said lid for allowing the passage of gas therethrough;
- said housing bottom sloping to at least one location to drain condensate to said at least one location;
- a filtered outlet port disposed in said housing bottom at each of said at least one location to allow the passage of condensate therethrough and for also allowing air compressed toward the housing bottom by the passage of steam through the lid to exit said housing;
- a pair of pedestal members for being coupled to the housing bottom on either side thereof for supporting the container and enabling stacking of a plurality of containers by cooperating with a lid of another container;
- and
- said domed lid and said sloping bottom dimensioned so that the inlet port of a lower container on said stack is positioned at a higher elevation than, and laterally offset from, the outlet port of the container immediately above said lower container throughout the sterilization process.
